“What then is that which is able to conduct a man?
One thing and only one, philosophy.
But this consists in keeping the daemon within a man free from violence and unharmed, superior to pains and pleasures, doing nothing without purpose, nor yet falsely and with hypocrisy, not feeling the need of another man’s doing or not doing anything;”
Aurelius, Marcus. Meditations . Pandora’s Box. Kindle Edition.
